Blind Spot: A Documentary Film

Blind Spot is a documentary that illustrates the current energy crisis that our way of life is facing. Whatever measures of greed, wishful thinking, neglect or ignorance, we have put ourselves at a crossroad which offers two paths, both with dire consequences. If we continue to burn fossil fuels, we will choke the life out of the planet, and if we don't, our way of life will collapse.

Water [electronic resource]: A Celebration

Nothing is so familiar, and yet so elusive, as water. A running faucet would require 136 trillion years to discharge the Earth's 326 million cubic miles of water, but only fresh water-less than three percent of the global supply-can sustain life. As we transport, utilize, and consume water, we are tempted to view it as eternally plentiful. But its protracted cycle of falling from the sky, seeping into the ground, resurfacing, and evaporating is a fickle, unwieldy process that makes water more precious than gold. This program investigates the uses and meaning of water in our lives.
